Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides a back-fire relief package for fire prevention, including back-fire relief bag 1, with by 1 sealed pearl rock stratum 2 and vermiculite 3 of back-fire relief bag in its inside, back-fire relief bag 1 includes glass fiber layer 11, glass fiber layer 11 is located back-fire relief bag 1 outmost, glass fiber layer 11's inside parcel has first supplementary flame retardant coating 12, the inside parcel of first supplementary flame retardant coating 12 has the supplementary flame retardant coating 13 of second, a plurality of recesses 4 have been seted up to glass fiber layer 11's top surface, and bottom surface fixed mounting has a plurality of sand grips 5, recess 4 and sand grip 5's size phase-match, recess 4 equals with sand grip 5 set up quantity, the equal fixed mounting in both sides surface of back-fire relief bag 1 has a plurality of joint pieces 6, the both sides surface at back-fire relief bag 1 is installed in the dislocation of a plurality of joint pieces 6, joint piece 6 is circular lug, a plurality of joint pieces 6 of back-fire relief bag 1 both sides equal.

In this embodiment, when using, at first pile up a plurality of back-fire relief bags side by side, and when piling up, carry out each back-fire relief bag butt joint between each back-fire relief bag through sand grip 5 and recess 4, make accumulational more stable between each back-fire relief bag, be difficult for empting, and, first supplementary flame retardant coating 12 and the supplementary flame retardant coating 13 of second have been installed additional in glass fiber layer 11's inboard, with glass fiber layer 11 block outside naked light together, greatly increased the back-fire relief performance of back-fire relief bag, piling up each other when placing back-fire relief bag 1, two adjacent back-fire relief bags 1 are through 6 mutual joints of joint piece, increase frictional force between the two, can effectually prevent that back-fire relief bag 1 from collapsing the condition after piling up and taking place.

Specifically, the outer side of the perlite layer 2 is in contact with the second auxiliary fireproof layer 13, a cavity is formed in the perlite layer 2, and vermiculite 3 is placed in the cavity.

In this embodiment, vermiculite 3 takes place to expand under the condition of high temperature, drives pearlite layer 2 by inside to outside and expands back-fire relief bag 1 for back-fire relief bag 1 more even of outside expansion can not appear because 3 expansions of vermiculite unevenly result in back-fire relief bag 1 shape irregularity to guide superimposed back-fire relief bag 1 to collapse.
